Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, and in particular to a temperature monitoring device for high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is a complete set of equipment used in power systems for controlling, protecting and distributing high-voltage electrical energy. It is typically applicable to voltage levels from 3kV to 35kV and mainly consists of circuit breakers, disconnecting switches, instrument transformers, surge arresters, busbars, cable terminals and control and protection devices. To ensure the normal use of high-voltage switchgear, its temperature needs to be monitored by a temperature monitoring device.

[0003] Existing temperature monitoring devices for high-voltage switchgear have some shortcomings in use: the devices usually perform integrated monitoring of the high-voltage switchgear without being specific, and cannot perform point monitoring of key parts of the high-voltage switchgear that are prone to heat generation (such as bus joints, circuit breaker contacts, and cable terminals), resulting in insufficient monitoring accuracy.

[0004] To address these issues, those skilled in the art have proposed a temperature monitoring device for high-voltage switchgear. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a temperature monitoring device for a high-voltage switchgear, which can realize multi-point monitoring inside the switchgear and achieve a more accurate monitoring effect. It includes a strip seat 100, which is installed on the inner wall of the switchgear.

[0032] Alarm mechanism 200 is mounted on strip base 100 and is located on the outside of switch cabinet;

[0033] Connecting mechanism 300, multiple connecting mechanisms 300 are mounted on strip base 100; and,

[0034] Temperature monitoring mechanism 400 is installed at one end of the corresponding connection mechanism 300. Temperature monitoring mechanism 400 is installed inside the switch cabinet for multi-point monitoring. Temperature monitoring mechanism 400 is electrically connected to alarm mechanism 200.

[0035] Specifically, the strip base 100 is installed on the top inner wall of the switch cabinet, and a slot 101 is opened on the bottom outer wall of the strip base 100. The connecting mechanism 300 is installed inside the slot 101.

[0036] In use, after installing the strip base 100 on the top inner wall of the high-voltage switchgear, the alarm mechanism 200 is placed on the outside of the switchgear. Then, the temperature monitoring mechanism 400 is moved through the connecting mechanism 300. The temperature monitoring mechanism 400 is installed in multiple locations inside the switchgear, such as bus joints, circuit breaker contacts, and cable terminals, for monitoring. Each component's temperature monitoring mechanism 400 corresponds to an alarm mechanism. When the temperature trigger threshold is detected, a signal is transmitted to the corresponding alarm mechanism 200. The alarm mechanism 200 alerts the staff to handle the situation in a timely manner to ensure that the switchgear can operate normally.

[0037] Example 2

[0038] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the connecting mechanism 300 includes a locking block 301, which is locked onto the inner wall of the slot 101. An elastic rope 302 is installed at the bottom of the locking block 301.

[0039] By moving the position of the movable card block 301 within the card slot 101 and stretching the elastic rope 302, the temperature monitoring mechanism 400 can be easily moved to any position within the switch cabinet for fixed-point monitoring.

[0040] Furthermore, the elastic rope 302 is divided into two layers: the inner layer of the elastic rope 302 is a silicone rubber core material 3021, and the outer layer of the elastic rope 302 is a braided aramid fiber reinforcing layer 3022.

[0041] The elastic rope 302 is composed of a silicone rubber core 3021 and a braided aramid fiber reinforcement layer 3022. The silicone rubber core 3021 provides elasticity and insulation, while the braided aramid fiber reinforcement layer 3022 improves tensile strength and abrasion resistance.

[0042] Furthermore, the outer wall of the woven aramid fiber reinforcement layer 3022 is coated with a titanium dioxide coating 3023.

[0043] Titanium dioxide coating 3023 enhances the UV aging resistance of elastic rope 302.

[0044] Furthermore, the temperature monitoring mechanism 400 includes a metal shield 401, inside which a single-point infrared thermometer 405 is installed, and a temperature probe 404 is installed at one end of the single-point infrared thermometer 405.

[0045] Furthermore, a silicone sealing layer 403 is installed at one end of the metal shield 401, a single-point infrared thermometer 405 is located inside the silicone sealing layer 403, and a temperature probe 404 is located outside the silicone sealing layer 403.

[0046] Furthermore, mounting plates 402 are fixed on both outer walls of the metal shielding cover 401, and the mounting plates 402 are fixed inside the switch cabinet near the monitoring point.

[0047] During use, the metal shield 401 and the silicone sealing layer 403 provide dust and moisture protection as well as electromagnetic interference resistance, ensuring that the single-point infrared thermometer 405 can perform temperature measurement normally.

[0048] Example 3

[0049] Reference Figure 1 and Figure 2This is the third embodiment of the present invention. Unlike the previous embodiment, the alarm mechanism 200 includes two connecting columns 201. The two connecting columns 201 are installed on both sides of the top outer wall of the strip seat 100. The top of the connecting column 201 passes through the top outer wall of the switch cabinet. Alarm components are provided on the surface of the two connecting columns 201.

[0050] Furthermore, the alarm assembly includes a connecting plate 202, which is mounted on the top outer wall of two connecting posts 201. The bottom of the connecting plate 202 is attached to the top outer wall of the switch cabinet. Multiple alarm lights 203 are installed on the top outer wall of the connecting plate 202, and the number of alarm lights 203 is the same as the number of single-point infrared thermometers 405.

[0051] When in use, the single-point infrared thermometer 405 is set with a temperature threshold. When the temperature at the bus joint, circuit breaker contact, cable terminal and other locations in the switch cabinet is high and exceeds the set temperature threshold, a signal will be transmitted to the corresponding alarm light 203. The alarm light 203 will then alert the staff to take timely action.

[0052] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
